I just tried your snippet on my machine and it worked fine:
{ "month": -3.8°C },
{ "month": -3.7°C },
{ "month": -4.9°C },
{ "month": 5.9°C },
{ "month": 9.2°C },
{ "month": 8.5°C },
{ "month": 5.7°C },
{ "month": 0.5°C },
{ "month": -1.2°C },
{ "month": -4.0°C },
{ "month": -4.0°C },
{ "month": -7.7°C },
What is the template /etc/weewx/skins/Seasons/curves_json.tmpl? It's not
part of WeeWX. Check it for errors.
